I posted this to erlang-bugs before, but got no response, so here's a 
new attempt. This time, the patch also has a test case courtesy of Uwe 

Because of a copy-and-paste error in erlc.c, the -MP flag had the same 
effect as -MG. As a workaround, you had to pass +makedep_phony to enable 
the MP option. This patch makes -MP work as intended.
